Chemical Structure
Description
2'-(Di-o-tolylphosphanyl)-[1,1'-binaphthalen]-2-ol (CAS 848191-69-5) is a high-purity analytical reference standard with the molecular formula C34H27OP and a molecular weight of 482.55 g/mol.
The molecular framework of 2'-(Di-o-tolylphosphanyl)-[1,1'-binaphthalen]-2-ol (C34H27OP) is characterized by organophosphorus functionality, a hydroxyl group, an ether linkage, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2'-(Di-o-tolylphosphanyl)-[1,1'-binaphthalen]-2-ol meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
